I have heard rumors that in the old days there were civilized black families with wonderful communities many decades ago.
Since I have never witnessed such things myself I have no choice but to classify them as rumors and myths.
I’ve lived among Black people all my life, half raised by a Black nanny. Those families existed and still exist today.
(I’ve noticed that White culture has certainly devolved, too - and the manner of some of the posters on FR are a perfect example of White cultural devolution.)
